' To allwhom it may concern:

Be it known that 1, J nssn G. Soooems, a'citizen of the United States,residing at Alva,

scope of devices of this character.

With these and other objects in view,which will appearas the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation, it being understood thatthe invention is not necessarily limited thereto, as various changes inthe shape, proportions, and general assemblage may be resorted towithout departing from the principle of the invention or sacrificing anyof its advantages.

In the drawings, Figure 1 is a side elevation partially in section, andFig. 2 is a plan view, of the improved device. Fig. 3 is an endelevation with the supporting-arm in section on the line 3 3 of Fig. 1.Fig. 4 is a sectional detail on the line 4: 4 of Fig. 2. Fig. 5 is atransverse section on the line 5 5 of Fig. 1.

The improved device is designed more particularly for use in connectionwith drillpresses and similar machines, but may be employed inconnection with other machines, if required, and I do. not, therefore,wish to be limited in any manner to any specific machine with which thedevice is to be associated.

The stocks or columns of drill-presses are usually tubular in form, andfor the purpose of illustration the device is shown applied to a portion10 of such a column; but as the drill-press or other machine forms nopart of the present invention it is not further illustrated.

The improved device comprises a head portion formed of spaced collars 1112 for encircling the supporting structure 10 and having an integralsplit collar 13, provided with a clampbolt 14 and also with an internalSpecification of Letters Patent.

socket 15. A stop-collar l6 encircles the supporting member 10 betweenthe collars 11112 and is provided with a set-screw 17 for bearing uponthe member 10, the collar 11 also having a set-screw 18 for bearing uponthe member 10. By this means the head portion may be adjusted verticallyupon the member 10 by means of the stop-collar and coupled movably atany desired point thereon by tightening the set-screw 17, and the headportion may also be rotated upon the member-Nor coupled rigidly theretoby tightening the setscrew 18, as will be obvious. 1

Mounted for rotation in the socket 15 in the head portion of the deviceis an arm 19, semicircular in cross-section exteriorly of .the splitcollar and circular within the same and with a terminalflange 20 toengage the socket. By this means the arm may be rotated to any desiredextent or rigidly coupled to the head portion by setting up theclamp-boltle, as will be obvious.

provided with inwardly-extending ribs 21 22,

spaced apart and forming the guiding-means for the viseportion of thedevice.

Bearing upon the arm 19 is a plate 23, having dovetailed side edges andwith a central bearing 24 depending between the ribs 21 22 and servingto guide the plate '23 longitudinally of the arm, while at the same timepermitting it to rotate freely thereon. p The arm 19 is also providedwitha longitudinal slot 25 through its lower rounded side, through whicha rod 26 passes and is threaded at the inner end for operating in athreaded aperture in the bearing 24, and alsoprovided 'with a shouldersupporting a clamp-washer The rod 26 terminates at the lower end in I ahand-wheel 28,.and by rotating this hand-- wheel in one direction theplate 23' will be. tightly clamped to the arm and released therefromwhen the rod is rotated in the opposite direction. Thus the plate may beadjusted longitudinally of the arm or rotated to any desired extentthereon and clamped rigidly in any position relative thereto.

Slidably disposed upon the plate 23 are two vise-jaws 29 30, the jaw 29having a setscrew 31 for rigidly coupling to the plate, and alsoprovided with a socket to receive the inner end of the operating-screw32, the latter having an annular groove (indicated at 33) in which atransverse pin 34 bears, as indi cated in Fig. 1. The operating'screw istappedthrough the other jawmemberand is provided with atransversely-sliding lever in its outer end. By this arrangement it willbe obvious that the vise-jaws may be adjusted upon the plate 23 to anyrequired position, and then the jaw 29 rigidly clamped thereon by meansof the 'clamp-screw 31, and the other jaw 30 adjusted to any desiredextent relative to the jaw 29 by rotating the operating-screw 32. Theadjacent faces of the jaw will preferably be provided with grooves 35 toreceive rods or pipes when the same are to be held between themtoincrease the grip. The jaws 29 30 are also provided with sockets toreceive supplemental clamping members 37 38 to extend the jaw members 293.0 when large bodies are to be held thereby.

It will thus be obvious thata simply-censtructed, com-pact, strong, anddurable device is produced capable of an extensive range of adjustmentsto adapt'it to a variety of uses and to hold the work no matter what itsshape or form and in any desired position.

Having thus described the invention, what is claimed is 1. In adevice ofthe class described, a supportingarm mounted for swinging movement, aretaining member mounted for longitudinal and pivotal movement-upon saidarm, a tool mounted for movement longitudinally of said retainingmember, and clamping means for securing said parts in their. adjustedpositions.

2. In a device of the class described, a supporting-arm havingalongitudinal guideway, a retaining member having a depending hearingengaging said guideway and rotatively and longitudinally movabletherein, a vise mounted for movement longitudinally of said retainingmember, means for securing said retaining member against movement uponsaid arm, and means for coupling said vise from movement upon saidretaining member.

3. In a device of the class described, a supporting-arm havinglongitudinal guideways, a retaining member-having dovetailed sides andwith a depending bearing for engaging said guideways and rotatively andlongitudinally movable therein, a vise having dovetailed lugs slidablyengaging said retaining member, means for coupling said retaining membersunset from movement upon said arm, and means for coupling said V188 formovement upon said guideways upon one side and a longitudinal slot uponthe opposite side, a retaining member'having-a depending bearing forengaging said guideway and rotatively and longitudinally movabletherein,a rod extending through said slot and having a threaded terminalengaging a threaded aperture in said bearing and with a washer bearingbeneath said guideways, a vise mounted for movement longitudinally ofsaid retaining member, and means for coupling said vise from movementupon said retaining member.

5. In a deviceof the class described, a suppnrting member,asupporting-arm, means for adjusting said arm longitudinally ofsaidsupporting member, means for connecting said arm for vertical andtransverse rotation relative to said supporting member, a retainingmember forlo-ngitudinal and rotative move ment uponsaid arm, meansfor-securing said retaining member against movement upon said arm, avise mounted for movement longitudinally upon said retaining member, and

'means for securing said vise against movement upon said retainingmember.

6. In a device of the class described, a head member comprising spacedcollars for enclasp-ing a supporting member and having an integral splitring provided with an internal socket, a supporting-arm having a bearingat one end for rotatively engaging said socket, means for clamping saidsplit ring to hold said bearing from rotative movement therein, aretaining member for longitudinal and rotative movement upon said arm, avi'se mounted for movementlongitudinally of said retaining member, meansfor clamping said retaining member from movement relative to said armand means for clam-ping said vise from movement relative to saidretaining member.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
